Redfish, do you think a 10000k bulb might do the trick? I did consider the fact that a blue bulb might cause a purple color. The blue one I'm considering is the aquablue from giesmann, which is actually a 15000k bulb.
Not a single 10,000K.
Maybe 2 10K, 1 6500, and one flora/red.
And some 10,000K bulbs, like the UVL Aquasun is also a Pepto-bismol pink. Really.
Personally I really like having a blue 460nm bulb (NOT an actinic, they are 420nm violet and a terrible choice for planted tanks).
My LEDs are basically 2:1 in white:blue ratio and power setting.
Give the blue a shot, you never quite know. I will say this, you'll have a very useful PAR spectrum since blue and red are the two most active photosynthetic colors.
